Daytime running light system
To make your vehicle more visible to other drivers, the front position lights turn
on automatically (at an increased intensity) whenever the hybrid system is started
and the parking brake is released. Daytime running lights are not designed for
use at night.
Headlight control sensor
Automatic light off system
When the light switch is in the or position: The headlights turn off
automatically if the power switch is turned to ACCESSORY mode or OFF.
When the light switch is in the position: The headlights and all lights turn
off automatically if the power switch is turned to ACCESSORY mode or OFF.
To turn the lights on again, turn the power switch to ON mode, or turn the light
switch off once and then back to the
or position.
Automatic headlight leveling system (if equipped)
The level of the headlights is automatically adjusted according to the number of
passengers and the loading condition of the vehicle to ensure that the headlights
do not interfere with other road users.
Light reminder buzzer (if equipped)
A buzzer sounds when the power switch is turned off or turned to ACCESSORY
mode and the driver’s door is opened while the lights are turned on. The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detect-
ing the level of ambient light and may cause
the automatic headlight system to malfunc-
tion.

Pulling the lever toward you can-
cels the cruise control.
The speed setting is also canceled
when the brakes are applied.
Pushing the lever up resumes the
cruise control and returns vehicle
speed to the set speed.
Resuming is available when the
vehicle speed is more than approxi-
mately 40 km/h (25 mph).
This mode employs a radar sensor to detect the presence of vehicles up to
approximately 120 m (400 ft.) ahead, determines the current vehicle-to-
vehicle following distance, and operates to maintain a suitable following
distance from the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long
downhill slopes.

Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise control in any of the following situations.
Doing so may result in inappropriate speed control and could cause an accident
resulting in death or serious injury.
In heavy traffic
On roads with sharp bends
On winding roads
On slippery roads, such as those covered with rain, ice or snow
On steep downhills, or where there are sudden changes between sharp up and
down gradients
Vehicle speed may exceed the set speed when driving down a steep hill.
At entrances to expressways
When weather conditions are bad enough that they may prevent the sensors
from functioning correctly (fog, snow, sandstorm, heavy rain, etc.)
When an approach warning buzzer is heard often
During emergency towing
When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles are
in front of you.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning (P. 237) will not be activated, and a fatal or serious acci-
dent may result.
Vehicles that cut in suddenly
Vehicles traveling at low speeds
Vehicles that are not moving
Vehicles with small rear ends (trailers with no load on board etc.)
Motorcycles traveling in the same lane

Conditions under which the vehicle-to-vehicle distance control may not func-
tion correctly
Apply the brakes as necessary in the following conditions as the radar sensor
may not be able to correctly detect vehicles ahead, and a fatal or serious acci-
dent may result:
When water or snow thrown up by the surrounding vehicles hinders the func-
tioning of the sensor
When your vehicle is pointing upwards (caused by a heavy load in the lug-
gage compartment etc.)
When the road curves or when the lanes are narrow
When steering wheel operation or your position in the lane is unstable
When the vehicle ahead of you decelerates suddenly
Handling the radar sensor
Observe the following to ensure the cruise control system can function effec-
tively.
Otherwise, the system may not function correctly and could result in an acci-
dent.
Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or dam-
age them.
Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunction. If
the sensor or surrounding area is subject to a strong impact, always have the
area inspected and adjusted by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
Do not disassemble the sensor.
Do not attach accessories or stickers to the sensor, grille cover or surrounding
area.
Do not modify or paint the sensor and grille cover.
Do not replace them with non-genuine parts.

The Lexus parking assist-sensor can be operated when
Front corner sensors:
• The power switch is in ON mode.
• The shift position is in other than P.
• The vehicle speed is less than about 10 km/h (6 mph).
(At any speed when the shift position is in R)
Rear corner and rear center sensors:
• The power switch is in ON mode.
• The shift position is in R.
Lexus parking assist-sensor display
When an obstacle is detected while the rear view monitor system or Lexus park-
ing assist monitor is in use, the warning indicator will appear in the upper corner
of the screen even if the display setting has been set to off.
Sensor detection information
The sensor’s detection areas are limited to the areas around the vehicle’s
bumper.
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an obstacle. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this
problem.)
• The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an
abnormal display, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines,
air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (lowered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are instances in which, because of
their shape, signs and other objects may be judged by a sensor to be closer than
they are.

When using the Lexus parking assist-sensor
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely and
possibly cause an accident.
Do not use the sensor at speeds in excess of 10 km/h (6 mph).
The sensors’ detection areas and reaction times are limited. When moving
forward or reversing, check the areas surrounding the vehicle (especially the
sides of the vehicle) for safety, and drive slowly, using the brake to control the
vehicle’s speed.
Do not install accessories within the sensors’ detection areas.
NOTICE
When using Lexus parking assist-sensor
In the following situations, the system may not function correctly due to a sen-
sor malfunction etc. Have the vehicle checked by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional.
The Lexus parking assist-sensor operation display flashes, and a buzzer
sounds when no obstacles are detected.
If the area around a sensor collides with something, or is subjected to strong
impact.
If the bumper collides with something.
If the display shows continuously without beeping, except when the buzzer
mute switch has been turned on.
If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.

PCS (Pre-Crash Safety system)
Pre-crash seat belts (front seat belts only)
If the pre-crash sensor detects that a collision is unavoidable, the pre-
crash safety system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or
loses control of the vehicle. (P. 4 1 )
However, when the VSC system is disabled, the system will not oper-
ate in the event of skidding.
Pre-crash brake assist
When there is a high possibility of a frontal collision, the system
applies greater braking force in relation to how strongly the brake
pedal is depressed.
Pre-crash braking
When there is a high possibility of a frontal collision, the system warns
the driver using a warning light, warning display and buzzer. If the sys-
tem determines that a collision is unavoidable, the brakes are automati-
cally applied to reduce the collision speed. Pre-crash braking can be
disabled using the pre-crash braking off switch.
: If equipped
When the radar sensor detects possibility of a frontal collision, the pre-
crash safety system such as the brakes and seat belts are automatically
engaged to lessen impact as well as vehicle damage.

2784-5. Using the driving support systems
CT200h_OM_OM76102E_(EE)
Conditions that may trigger the system even if there is no possibility of a collision
When there is an object by the roadside at the entrance to a curve
When passing an oncoming vehicle on a curve
When driving over a narrow iron bridge
When there is a metal object on the road surface
When driving on an uneven road surface (nose up, nose down)
When passing an oncoming vehicle on a left-turn (left-hand drive vehicles) or
right-turn (right-hand drive vehicles)
When your vehicle rapidly closes on the vehicle in front
When a grade separation/interchange, sign, billboard, or other structure appears
to be directly in the vehicle’s line of travel
When the steep angle of the road causes a metal object located beneath the road
surface to be seen ahead of the vehicle
When an extreme change in vehicle height occurs
When the axis of the radar is out of adjustment
When passing through certain toll gates
When passing through an overpass
When passing through a tunnel
When the system is activated in the situations described above, there is also a
possibility that the seat belts will retract quickly and the brakes will be applied
with a force greater than normal. When the seat belt is locked in the retracted
position, stop the vehicle in a safe place, release the seat belt and refasten it.
Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may also
be occasions when the sensor cannot detect pedestrians, animals, bicycles,
motorcycles, trees, or snowdrifts.
Situations in which the pre-crash safety system does not function properly
The system may not function effectively in situations such as the following:
On roads with sharp bends or uneven surfaces
If a vehicle suddenly moves in front of vehicle, such as at an intersection
If a vehicle suddenly cuts in front of vehicle, such as when overtaking
In inclement weather such as heavy rain, fog, snow or sand storms
When your vehicle is skidding with the VSC system off
When an extreme change in vehicle height occurs
When the axis of the radar is out of adjustment
Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in the
sensors being unable to detect obstacles, the pre-crash safety system will be auto-
matically disabled. In this case, the system will not activate even if there is a col-
lision possibility.
